Twilight star Kristen Stewart has shown off her generous side by donating a pair of signed shoes to charity. The actress scrawled her autograph on a pair of black sneakers and handed the footwear to charity Shoe Revolt to help victims of human trafficking.

The organization sells shoes online to raise funds to fight the cause.

A statement from the charity reads, “Shoe Revolt is incredibly thankful for Kristen Stewart’s donation of a pair of black Keds. Her donations will be used to raise money for shelters and to create awareness about this issue in the teen community.”
